Collin Horn (PhD)

Research Interests:

I am interested in the ecology and ecological physiology of parasite-host interactions. My research examines how differences in host physiology, in particular metabolic rate, affect infection outcomes/intensities. On an ecological scale, I am interested in the effects parasites have on host populations, particularly outside of infection.
